When a time probe executes, it records the time, the - // id of the calling thread, and an event description. The - // event description can either be an unsigned long or a string - // (char *). If string are used, care must be taken cause only - // pointer copies are done and the string data is *not* copied. - // - // The recorded time probes can then be printed by calling - // print_times(). If you have used unsigned longs as event - // descriptions in any of your time probes, you must have - // provided an event description table that maps the unsigned - // longs to readable strings. This map is a simple array of - // strings, and the event number is used as the index into the - // array when looking for the event description. If you have - // only used strings for the event description, this map is not - // necessary. - // - // Multiple maps can also be used to chunk up the time probes. - // Each one can be added by calling event_descriptions(). - // Different tables are used internally by consulting the - // minimum_id for each table.
